Abstract

Provided is a technique for automatically extracting a cross section with a high degree of precision and at high speed, with avoiding problems of operator dependence and imaging target dependence, from 3D volume data or temporally sequential 2D or 3D images or 3D volume data, acquired by a medical imaging device, when determining the cross section used for diagnosis and measurement. An image processor of an imaging device is provided with a cross section extractor for extracting a specified cross section from imaged data. The cross section extractor determines the specified cross section by using a learning model trained in advance to output discrimination scores for a plurality of cross sectional image data, the discrimination score representing spatial or temporal proximity to the specified cross section. The learning model is a downsized model obtained by integrating a highly trained model having a large number of layers, with an untrained model having less number of layers, followed by retraining.

Description

TECHNICAL FIELD

[0001] The present invention relates to a medical imaging device, including an ultrasound imaging device, an MRI device, and a CT device. More particularly, the present invention relates to techniques for selecting a specified cross section to be displayed, from a three-dimensional image, or two-dimensional (2D) time-series images or three-dimensional (3D) time-series images, being acquired by the medical imaging device.BACKGROUND ART

[0002] Medical imaging devices are used to acquire and then display a morphological image of a target region. In addition, the medical imaging devices can also be used to acquire morphological information and functional information quantitatively. One of examples of such usage may be measurement of estimated weight of an unborn baby (fetus) for observing growth thereof, by the use of an ultrasound imaging device. This type of measurement is performed according to a process, roughly divided into three steps; acquiring images, selecting an im...
